Product overview

Description

SPSA068 is a BUCK voltage regulator with a precise voltage reference for MCU applications. All the regulators have internal power switches.

The LPM allows the operation under light-load conditions reducing the quiescent current down to 50 μA typ.

An internal programmable memory allows selecting the main device parameters like output voltages and switching frequencies.

An SPI interface can be used for diagnostics, programming, monitor and external window watchdog.

The device offers a set of features to support applications that need to fulfill functional safety requirements as defined by automotive Safety Integrity Level.

  • All features

    • AEC-Q100 qualified
    • Pre SMPS BUCK regulator, adjustable via NVM to 5.0 V and 3.3 V at 0.5 A and 1.0 A load current, 0.4/2.4 MHz.
    • Precise voltage reference (1%), adjustable via NVM to 5.0 V and 3.3V at 20 mA load current
    • Standby mode Iq < 5 μA
    • Low quiescent current, 50 μA, in low power active mode
    • SPI interface with CRC
    • Programmable soft start
    • Voltage supervisors
    • Spread frequency spectrum
    • Reset output
    • Adjustable window watchdog supervisors
    • VREF, tracking of VBUCK in power-up phase
    • Short circuit protected outputs and Fault detection pin to microcontroller
    • Low external components number
    • Thermal warning and thermal shutdown
